Assume that run A had A.P0, A.P1 and run B had B.P0, B.P1, B.P2, B.P3 and assume that A.P0 did the same work as B.P0 and B.P1 and A.P1 did the same work as B.P2 and B.P3.
To get a meaningful Comparison Message Profile under these assumptions, choose the aggregation as shown in here and here:
Intel® Trace Analyzer
This image demonstrates the comparison of Run A (with 2 processes) with Run B (with 4 processes).
The message profile shows the average transfer rate quotient B/A. The Comparison Message Profile (and in fact the whole Comparison View) maps the senders and receivers of the two runs onto each other in the following way: child number i of run A's process aggregation is always mapped to (compared with) child number i of run B's process aggregation.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
